“…The chemical module (CaO + MgO + Al 2 O 3 )/SiO 2 controlled the reactivity of slag. With a high modulus, mineral additions may be more reactive, which has led to the concept of ternary mixture [40]. The test results show similar trends to the compressive strength.…”

“…The fineness of the slags was also determined based on TS EN 196-6 (2010). The basicity index (BI) and chemical modulus ratio ([CaO + MgO]/SiO 2 ) of the slags were calculated as a measure of slag reactivity according to the equations suggested by Bauné et al (2000) and Wainwright and Rey (2000), respectively. Obtained results considering also the slag composition were given in Table 1.…”

“…To ensure high alkalinity, without which slag would be hydraulically inactive, European Standard ENV 197-1:1992, recommend that the ratio of CaO + MgO to SiO 2 exceeds 1. (Luo et al 2003, Yun Yeau andKim 2005); reducing p and drying shrinkage yong and Yan 2001); sing sulfate resistance (Higgins 2003, Binici and 006); enhancing the ultimate compressive strength (Barnett et al 2006) and reducing the heat of hydration and bleeding (Wainwright and Rey 2000). GGBS also improve concrete workability due to its high specific surface, marketed at 375-435 m 3 /kg with a fineness of approximately 460 Blaine (m 2 /kg.min).…”

Ordinary Portland cement (OPC) has been traditionally used in the construction of concrete silos in Ireland. However, the aggressive nature of the effluent produced by silage leads to severe degradation of the concrete. GGBS is a common addition to PC composites. It has been demonstrated that GGBS improves the general performance of PC concrete decreasing chloride diffusion and chloride ion permeability; reducing creep and drying shrinkage; increasing sulfate resistance; enhancing ultimate compressive strength and reducing heat of hydration and bleeding. It has also been suggested that GGBS may increase concrete durability in the aggressive environment of silos. In order to investigate this theory, a simulation study was carried out by immersing samples of mortars incorporating increasing amounts of GGBS in a silage effluent solution and a magnesium sulphate solution. Over the course of an experiment consisting of three, 28-day cycles of immersion in the silage effluent, the sample performance was evaluated by testing permeability, porosity, water absorption, capillary suction, compressive strength and mass loss. According to the results obtained, the OPC samples suffered the highest rise in permeability and porosity and the greatest loss in both mass and compressive strength. In addition, the durability of the mortars, when subjected to both salt crystallisation and silage effluent cycles, increased with increasing amounts of GGBS. The significant rise in capillary suction, water absorption and permeability over the course of the experiment indicates that the damage induced by the effluent is not as superficial as previously reported. Loss in mass and increase in permeability were found to be the most reliable indicators of corrosion as they gave the most dramatic and uniform results.
